SIGHT GAUGE Application filed October 19, 1931. Serial` No. 569,805.

The present invention has to do with certain advantageous kfeatures and advantages embodied in an improved sight gauge usedin a fluid line for indicating the flow of the fluid,

5v and the improvement has specic reference to a gauge designed to accommodate the passage of gasoline, alcohol, and otherinflammable liquids. Y

By Way of introduction it is to be stated I0 that the novelty is predicated particularly on the improved packing or gasket assembly embodied in the gauge and the peculiar adaptation of said packing for the gauge Without requiring alterations of the kparts of the 15 gauge. e

More explicitly stated, the gauge, which is of a Well-known type, embodies an openended glass cylinder with metallic closures for the ends of the cylinder and means for s ecurely binding or bolting the closures 1n place. A

At the present time, and in the type of gauge illustrated in the'drawing, the inner faces of the closures are grooved, and fitted in each groove is a cork packing ring and an associated litharge seal.

The foregoing seal is characterized by objections which the present invention is designed to overcome, for instead of using the cork packing ring and an adhesive seal, I substitute novel iiber composition gasket rings interposed between the ends of the glass cylinder and the adjacent faces of the c losures in order to provide a more eii'ectlve 35 union.

The gist of the invention is, therefore, in the provision of composition fibre gaskets held in place by the conventional clamping bolts and susceptible of providing the requisite oints Without the use of cement, litharge and glycerine or any other viscous substance.

The feature of the invention is in the provision of a novel joint of this type susceptible of retaining gasoline, benzol, naptha, alcohol and other penetrating acid laden liquids.

In the drawing:

Figure 1 is a top plan view of the type of gauge under consideration.

r Figure 2 is a horizontal section With the improved gasket means in place.

Figure 3 is a verticalsection disclosing further the'upper and loWer gaskets in operative position. j

\ Figures 4;, 5 and 6 are fragmentary sectional perspectiveV views showing the dilfermi ent cross sectional i configurations of the Y gasket.v Y

It is understood that no novelty is claimed for the specific construction of the gauge eX- cept as it is materially improved bythe pres- 60 ence of the novel 'gasket contemplated to avoid leakage and to convert the otherwise objectionable gauge linto one which is more satisfactory in the handling of acid liquids.

Itis understood, in this connection that in handling' liquids of this variety, rubber'packing rings Will not do, nor will the present joint embodying cork and adhesive features serve the desired result. y Y.

In Figure 3, the open-ended glass cylinder "0 is denoted by the numeral 7 the top closing' plate by' the numeral 8 and the baseV or bot tom closing plate by the numeral 9. As is A customary'in a gauge of thisY type, the' plate y 9 is formed With a central fluid outletsnipple 10 and an intake neck 11. v Then too,-on the interior are supports 12 for the rotary bladed indicator 13 (zo-'operable with an adjacent baile 14. v Y

The connective bolts are'indicated by the numerals 15 and the Wing retaining nuts by the numerals 16. The numerals l17 merely designate spacing struts to limit Vthe bolt tightening action and to prevent breakage of the glass. Ordinarily the inner faces of these 5 plates 8 and 9 are grooved to receive the ends of the glass cylinder and it is betvveeny these faces and ends that the adhesive and'present cork packings are interposed.

In actual practice I provide grooved packing rings or gaskets each ring being designated by vthe numeral 18. A special fibre composition is employed in the manufacture of these rings. I do not claim invention in the particular texture of the ring itself, but in a ring Whose properties provide the requi` site resiliency and acid-proof and leak-proofl features.

In the dravving I have shovvn fourdifferent species of gasket rings, each ring being sub-1 the numeral 2l in Figure 6 a substantially semi-circular groove.

It is evident, of course, that the shape of the edge of the glass must correspond to the shape of the groove. The upper and lower. gaskets in Figure 3 are seated in the grooves of the plates 8 and 9 and the bolts tightened in the usual way to provide the desired seal and leak-proof union.

e Heretofore, so far as I know, gauges of this type are leaky, due to deterioi'ation from the acid liquid or from inappropriate compositions of the materials used in constructing ,.-gasketa Moreover, since these gauges are subject to breakage and require repair at frequent intervals, considerable time, labor and expense yis attached to the reinstallation of present-day type of packing, which, as before stated, comprises a cork ring of flat crosssectional shape, and litharge or equivalent adhesive sealing compounds.

This sealing compound in actual practice requires a minimum of fou-r hours to set. As only one end can be litharged at one time, it necessitates a pump being shut down for approximately eight hours to allow the litharge to set and the gauge to be reinstalled. Therefore, by substitutingl these improved libre packing rings, the gauge can be completely repaired and put back in place in an exceptionally short time, and inasmuch as the material is acid proof, the longevity of the union or joint is maintained indefinitely.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and inthe combination and arrangement ofthe several parts provided that such changes fall within the scope of the appended claims.

I claim:

l. In a structure of the class described, in

combination, an open-ended visible glass cylinder, metal closing plates for the opposite ends'thereof, the inner faces of said plates being grooved, clamping bolts for maintaining said plates in closing relationship, spacing struts interposed between the plates for limiting the clamping pressure of said bolts, and gaskets interposed 'between the plates and ends of said cylinder, said gaskets beingV seated in the grooves in saidplates, each gasket being of general rectangular cross Lsvmsoe sectional shape and formed with a groove gaskets interposed between the plates and ends of said cylinder-,said gaskets being seated in the grooves in said plates, each gasket being of general rectangulary cross sectional shape and formed with a groove for reception of the adjacent endA of thercylinder, each gasket being composed. of acid-proof iibrous material for the purpose stated, the groove in each gasket being substantially semi-hexagonal in shape, the adjacent end ofthe cylinder being of corresponding shape to lit into said groove.

3.V In a structure of the class described, in combination, an open-ended visible glass cylinder, metal closing plates for the opposite ends thereof, the inner faces of said plates being grooved, clamping bolts for maintaining said plates in closing relationship, spacing struts interposed between the plates for li1nitinf, ,ry the clamping action Aof said bolts,

and gaskets interposed between the plates and ends of said cylinder, 'said gaskets being seat-A ed in the grooves in said plates, each gasket being of general rectangular cross sectional shape and formed with a groove for reception of the adjacent end of the cylinder, each gasket being composed of acid-proof fibrous material for the purpose stated, the groove in saidgasket being substantially V-shaped.

In testimony whereof I affix lmy signature.
